Proportional or Non- Proportional?
This table compares the number of hours (x) to rent a bicycle to the total cost in dollars (y).
This graph shows an hourly bicycle rental. The graph is a straight line and starts at (0,0).
It cost $5 for 1 hour of a bike rental.
I think it is proportional because the line can keep on going in the graph. The ratios are all times by the same number, so they are all equivalent ratios. A proportion is a realationship between two quantities that reduce to the same ratio.
